Description

Technical Field

[0001] This utility model relates to the field of hot runner system technology, and in particular to a novel dual-piston small-pitch cylinder base structure. Background Technology

[0002] See Figure 1 Traditional cylinder bases consist of a lower base 1 fixed to a manifold and an upper base 2 mounted on the lower base 1 for fixing the cylinder. If a conventional cylinder is used and mounted on the upper base 2, the minimum center-to-center distance between the cylinders must be 53mm, which cannot meet the requirements for small product spacing. If the product spacing is large, it will increase the volume of adhesive in the hot runner, resulting in a longer residence time for the adhesive and an increased risk of adhesive carbonization. Thus, conventional cylinders cannot meet the customer's requirements.

[0003] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel dual-piston small-pitch cylinder base structure to solve the interference between ordinary cylinder blocks, thereby solving the above-mentioned problem.

[0005] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0006] A novel dual-piston small-pitch cylinder base structure is characterized by comprising a cylinder base structure disposed on a manifold plate for fixing a conventional cylinder, the cylinder base structure comprising a first base disposed on the manifold plate and a second base disposed inside the first base for fixing the conventional cylinder.

[0007] In a preferred embodiment of the present invention, the first base has a cavity in the middle for mounting the second base, and the first base has a cylindrical structure.

[0008] In a preferred embodiment of this utility model, the second base is provided with several through holes around its perimeter.

[0009] In a preferred embodiment of this utility model, the second base is provided with a mounting hole in the middle for use with a conventional cylinder.

[0010] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: Compared with the traditional cylinder base, the conventional cylinder requires a minimum center distance of 53mm between cylinder bodies, which cannot meet the needs of customers with small product spacing (if the customer's product spacing is large, it will increase the volume of glue in the hot runner, resulting in a longer residence time of the glue and an increased risk of glue carbonization). Thus, the conventional cylinder cannot meet the customer's requirements. Therefore, the cylinder base structure of this utility model can reduce the center distance between product points to within 38mm. The cylinder base structure shortens the cylinder interference problem caused by the close spacing of the points. At the same time, due to the optimization and improvement of the structure, its function is more complete, better meeting customer needs and giving full play to its own advantages.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] See Figures 2 to 3 The present invention discloses a novel dual-piston small-pitch cylinder base structure, including a cylinder base structure 10 disposed on a manifold and used to fix a conventional cylinder. The cylinder base structure 10 includes a first base 11 disposed on the manifold and a second base 12 disposed inside the first base 11 and used to fix a conventional cylinder.

[0017] The first base 11 has a cavity 11a in the middle for mounting the second base 12. The first base 11 has a cylindrical structure.

[0018] The second base 12 has several through holes 12a around its perimeter. In this embodiment, there are four through holes 12a, which can be fixed to the first base 11 by bolt assembly. The second base 12 has a mounting hole 12b in the center for use with a conventional cylinder.

[0019] Compared with the prior art, this utility model transforms the original two separate parts into a single base, which is now made up of a single part with a smaller diameter. By using a cylinder base structure 10, the center-to-center distance of the product points can be reduced to within 38mm. The cylinder base structure 10 also reduces the problem of cylinder interference caused by the close distance between points. Furthermore, the optimization and improvement of the structure make its functions more complete, better meet customer needs, and give full play to its advantages.
